植物光合生理及环境监测系统——PTM-48A
可实现植物光合速率、生理指标和环境因子的同步连续监测
PTM-48A是一台光合仪,但它不是一台普通的光合仪。它专为长期连续监测而设计,监测时间可长达数周。特殊的自动开合式叶室,可将叶室关闭对叶片生长的影响降到*低。4个叶室通道的设计,使研究者可同时监测多个植株或叶片。
PTM-48A是一台光合仪,但它不仅仅是一台光合仪。它还是一台多通道植物生理及环境监测系统。它可以连接多达8个传感器通道,实现对环境因子(PAR、空气温湿度、土壤温湿度等)和植物生理指标(叶片温度、茎流速率、茎杆微变化、果实生长量等)的同步监测。
主要功能
|
PAR等多项环境和生理指标
|
在亚洲的韩国和日本,用户利用该系统进行生长箱中作物的长期监测。
测量参数
光合气体交换测量值:CO2同化速率、蒸腾速率、气孔导度、参比和叶室CO2浓度、参比和叶室H2O浓度、叶室空气流量、水汽压饱和亏、大气压等
外接传感器测量值:植物茎流量、茎杆微变化、树干直径生长量、果实生长量、叶面温度、PAR、空气温湿度、土壤温湿度等
主要技术参数
可附加:土壤温度、含水量和电导率3 in 1传感器。
应用举例:
下图是棉花叶片一天的监测结果,这只是一部分传感器的数值对照,该系统可以得到多个传感器数值对照图形,使试验结果更清晰的表现在图上,这样对于研究环境因子变化对植物生理影响更加方便。
